WEDNESDAY, March 7, 2018 -- Breast cancer screening guidelines are based mainly on scientific data from white women, and that bias could cause delayed detection of the disease in minorities, researchers report.

"While a lot of attention has been focused on improving the 'cultural competency' of clinical care -- caring for patients in ways that accommodate their cultural and language differences -- we are concerned that we haven't paid as much attention to the scientific research process," said David Chang, from Massachusetts General Hospital's department of surgery.

FRIDAY, April 13, 2018 -- While only 5 percent to 10 percent of cancers are caused by an inherited gene mutation, genetic testing may benefit people with a strong history of family cancer, an expert in genetics suggests.

This is especially true in families with a history of breast, ovarian, prostate or pancreatic cancers (especially if you are of Ashkenazi Jewish descent), as well as colon and uterine cancers, said Monique Lubaton. She is a cancer genetic counselor at LifeBridge Health in Baltimore.

THURSDAY, March 22, 2018 -- After American women began to adopt annual mammography screening in the 1980s, a very healthy thing happened: the average size of newly discovered breast tumors got smaller.

That's the finding from a new look at data on more than 386,000 U.S. women who were diagnosed with breast cancer between 1983 and 2014.

The study of more than 300 women who underwent breast radiation found that almost half had heard "frightening" stories going into treatment. But only 2 percent ultimately agreed that the stories were true.
